A novel heterocyclic based β-diketone has been synthesized by the condensation ofpyrazole-1-acetylchloride and sodium acetophenone. The product 1-phenyl-4-(pyrazole-1-yl)butane-1,3-dione has been used for complexation with Mn(II), Fe(II) and Co(II) metal ions. The ligandβ-diketone is found to exist in keto-enol tautomeric forms. The comparision of infrared spectra ofcomplexes clearly indicates the coordination of the ligand from its enolic form. The magnetic momentand electronic spectra of all the metal complexes leads to the distorted octahedral symmetry aroundthe metal ion. The ligand as well as its metal complexes has been screened for antimicrobial activityand antifungal activities. It is observed that the antimicrobial and antifungal activities get enhanced incomplexes in respect to the free ligand.
